Whilst these events had been passing in Austria and Bavaria, the King of England had endeavoured to make a powerful diversion in the Netherlands. Under the plea of this movement sixteen thousand British troops were embarked in April for the Netherlands; but they were first employed to overawe Prussia, which was in contention with Hanover regarding the Duchy of Mecklenburg. There were other causes of dispute between Prussia and the Elector of Hanover. George having now this strong British force, besides sixteen thousand Hanoverian troops and six thousand auxiliary Hessians, Frederick thought proper to come to terms with him, and, in consequence of mutual arrangements, the Hanoverian troops quitted Mecklenburg, and George, feeling Hanover safe, marched this united force to the Netherlands to join the British ones. He expected the Dutch to co-operate with him and the Austrians, and strike a decided blow at France. But the Earl of Stair, who was to command these forces, and who was at the same time ambassador to the States, found it impossible to induce the Dutch to act. They had increased their forces both by sea and land, but they were afraid of the vicinity of the French, and were, with their usual jealousy, by no means pleased to see the English assuming power in the Netherlands. Therefore, after making a great demonstration of an attempt on the French frontier with the united army, the project was suddenly abandoned, and the troops retired into winter quarters. But little was accomplished during this year by the British fleet.
The Session of 1753 was distinguished by two remarkable Acts of Parliament. The one was for the naturalisation of the Jews, the other for the prevention of clandestine marriages. The Jew Bill was introduced into the Lords, and passed it with singular ease, scarcely exciting an objection from the whole bench of bishops; Lord Lyttelton declaring that "he who hated another man for not being a Christian was not a Christian himself." But in the Commons it raised a fierce debate. On the 7th of May, on the second reading, it was assailed by loud assertions that to admit the Jews to such privileges was to dishonour the Christian faith; that it would deluge the kingdom with usurers, brokers, and beggars; that the Jews would buy up the advowsons, and thus destroy the Church; that it was flying directly in the face of God and of Prophecy, which had declared the Jews should be scattered over the face of the earth, without any country or fixed abode. Pelham ridiculed the fears about the Church, showing that, by their own rigid tenets, the Jews could neither enter our Church nor marry our women, and could therefore never touch our religion, nor amalgamate with us as a people; that as to civil offices, unless they took the Sacrament, they could not be even excisemen or custom-house officers. The Bill passed by a majority of ninety-five to sixteen; but the storm was only wafted from the Parliament to the public. Out-of-doors the members of Parliament, and especially the bishops, were pursued with the fiercest rancour and insult. Members of the Commons were threatened by their constituents with the loss of their seats for voting in favour of this Bill; and one of them, Mr. Sydenham, of Exeter, defended himself by declaring that he was no Jew, but travelled on the Sabbath like a Christian. The populace pursued the members and the bishops in the streets, crying, "No Jews! No Jews! No wooden shoes!" In short, such was the popular fury, that the Duke of Newcastle was glad to bring in a Bill for the repeal of his Act of Naturalisation on the very first day of the next Session, which passed rapidly through both Houses.
Wilberforce, on the 27th of January, had obtained a committee of inquiry into the slave trade. He, Clarkson, and the anti-slavery committees, both in London and the provinces, were labouring with indefatigable industry in collecting and diffusing information on this subject. The Committee of the Commons found strong opposition even in the House, and, on the 23rd of April, Lord Penrhyn moved that no further evidence should be heard by the Committee; but this was overruled, and the hearing of evidence continued through the Session, though no further debate took place on the question.Here all further progress became impossible. The Spaniards having reduced their debt to less than one half the original sum, were fighting stoutly to reduce it to nothing. There appeared no chance but for arms to decide it. Cardinal Fleury, with his usual pacific disposition, made an effort to avert the war by guaranteeing to undertake the payment of the ninety-five thousand pounds by Spain, provided that the British fleet was withdrawn from the Mediterranean. But English spirit, even in Walpole, had now reached its limit of patience. The king and the nation were equally in a mood for war. Walpole, therefore, ceased to listen any longer to the Spanish objections, but took his stand on the true British ground of resistance to the right of search, and on that of an acknowledgment of all British rights and claims in North America. Instead of withdrawing the Mediterranean fleet, he ordered its reinforcement, sent Sir Chaloner Ogle with fresh ships to the West Indies, and Sir John Norris was ordered to put to sea with a third squadron. The above demands being peremptorily made from the Court of Madrid, and being rejected, war was proclaimed in London on the 19th of October. Walpole, who had reluctantly resorted to this master evil, as he heard the rejoicings, exclaimed, "They may ring the bells now, but they will soon be wringing their hands!" The first symptoms of the consequences which the war was likely to produce were seen in the new hopes which it awoke in the ranks of the Jacobites. Large numbers of them met at Edinburgh, and drew up a bond of association, pledging one another to take arms and venture life and fortune for the restoration of the Stuart. On the other hand, those nations on which England calculated for aid hung back and remained neutral. The Dutch were bound to furnish certain troops in case of war, and, before the declaration of it, Horace Walpole was despatched by his brother to demand their production; but they pleaded the menaces of France, which threatened them with invasion by fifty thousand men if they assisted the English, and which held out to them the prospect of their obtaining that trade to the Spanish colonies which England had enjoyed. As for France herself, she assumed an air rather ominous of war than of peace, and thus Britain was left alone in the contest.
